1 SECTION 4.5 PAGE 1 / 5 l DESCRIPTION The UCAN Scru-it masonry anchor is manufactured to strict specifications from high quality steel. The proprietary, UCAN designed, scalloped thread cuts deep grooves in a wide variety of masonry materials (solid concrete, block, brick etc.) producing up to three times the holding power of comparable anchors. l FEATURES High strength Close to edge fastening No spalling, cuts cleanly into pre-drilled hole Fast and easy installation Removable Diamond point for easy centering RUSPRO coated for maximum corrosion resistance Available in Stainless Steel Available head styles (Hex head, Flat head with Phillips and Square socket) Available in bulk l TYPICAL APPLICATIONS Conduit clips Strapping or 2x4 studs Metal shelf - uprights Cladding Window frames Brick ties l MATERIAL SPECIFICATIONS Anchor Body Carbon Steel: AISI C1022 UTS: 73 ksi (503 MPa) Case Hardened (HRC: 30-42) Stainless Steel: AISI 410 C UTS: 78 ksi (538 MPa) l CORROSION PROTECTION Ruspro coating: Multi layer coating provides superior corrosion resistance to sulphur dioxide, salt spray, acids and alkalis as well as having excellent abrasion resistance. Available in blue and silver (Square socket type) colours. HOURS TO RED RUST * Passivated Passivated & Zinc Plated Ruspro II Per ASTM B117. Test performed on uninstalled fasteners.

2 SECTION 4.5 PAGE 2 / 5 l DESIGN DATA FOR INSTALLATIONS AFFECTED BY VARIOUS ENVIRONMENTAL CONDITIONS Reliable fastener design requires fastener performance data in various environmental conditions since the fastening assemblies cannot always be inspected and maintained. UCAN Fastening Products engaged in a comprehensive test program to provide these important data to support correct fastener selection. ORTECH Corporation, an ISO 9002 Canadian Testing Agency performed the following test program: Tension and Shear Loading in three different substrates i.e. 30 MPa concrete, concrete hollow and solid block under the following environmental conditions: (see details on page 3) ambient laboratory conditions 100% saturation to simulate exposure of substrate and fastener to rain cold temperature exposure of substrate and fastener at -20 C Abrasion resistance testing Galvanic corrosion test Galvanic corrosion test data 100 Galvanic corrosion starts Zinc plated 75 Exposed surface corrosion (%) Red rust White rust RUSPRO coated Galvanic corrosion starts Hours of salt spray (ASTM B117-94) Abrasion Resistance Test RUSPRO coated fasteners were installed into hollow concrete block under normal and over-torque conditions. The fasteners were examined under binocular microscope at 7x magnification. After the visual inspection, the specimens were cut to reveal their cross section and were examined metallographically. The test results indicated slight removal of coating at the points of the hex head. None of the specimens displayed damage to the case hardening, indicating the fasteners excellent resistance to abrasion.
